Hi. Thanks for the files. They are quite interesting, but i did forget to mention that i was looking for shapefiles containing borders from 1946 to 2005.

Actually, I may be able to help you a little bit...

I have atlases/world maps from the following years in my collection:1936, 1958, 1960, 1967, 1968, 1970, 1986, 1988 and 1999. I could make scans or photos of those maps which you could use as a reference (though they'd be in different styles, scales and projections).

Thanks for the link. I used those shapefiles to make this animated exhibit in google earth:

Hi,

I am replying to this old post to answer my own question.Last year the cShapes dataset was introduced both as shapefile and as a R-package. The project is led by Nils Weidmann (Princeton Uni.) and Kristian Skrede Gleditsch (Uni. of Essex, UK).

Resurrecting this thread to see if there's an interest in a proper set. I've attached that collection that I mentioned (again with the caveat that I have no idea who did it, whether or not it's public domain and am aware the quality isn't great)

What I'd really like to see is a new set, public domain, based on Natural Earth Vector 10M for at least the key times in the 20th/21st century:

1900

1914 (before WW1)

1920 (after Versailles Treaty kicks in)

1938 (after German annexation of Austria and Sudetenland)

1946 (after WW2)

somewhere in the middle of the decolonisation period)

1989 (before fall of communism)

2000

Would there be an interest in this? I get on average 2-4 requests per year for that original set of shapefiles and am always happy to provide them. Would we benefit from the added accuracy we get from hooking it up to NEV? Would there be volunteers to help me out?
